Definitions

  • the invention is based on a valve according to the preamble of the independent claim.
  • valves are known for example from DE 197 53 575 A1.
  • the valve described in DE 197 53 575 A1 is a magnetic bypass valve for a fluid-controlled heating or cooling system.
  • Two valve members mounted on a lift rod of the valve control the flow between an inlet channel and two outlet channels, one of these outlet channels acting as a bypass channel in the heating or cooling circuit.
  • a disadvantage of the valve described in DE 197 53 575 A1 and all comparable valves is - due to the design - the rather complicated assembly of the individual components of the valve. First, the sealing rings, which form the valve seats of the valve chamber and a spacer sleeve, which limits the actual valve chamber of the valve to be pushed onto the lifting rod of the valve.
  • bypass valve member mounted on the lifting rod and secured with a lock washer on the lifting rod.
  • the pre-assembled unit consisting of the lifting rod, bypass valve member, valve seats and spacer is pushed into the valve body and the individual components are set in position.
  • a further spacer sleeve for fixing the valve chamber must be introduced into the valve housing and only then can the second valve member to control the Nutzausgangs be mounted on the lifting rod.
  • the assembly described is cumbersome, consuming and therefore expensive.
  • the attachment of the valve members to the lifting rod is expensive to secure by a groove in the lifting rod and an additional locking washer.
  • valve according to the invention with the features of the main claim has the advantage that a faster and improved assembly in the manufacture of valves is possible.
  • the assembly sequence is almost independent of the time of installation of the lifting rod in the valve housing, since the lifting rod can be introduced later with the fixed valve members even in the valve chamber.
  • An elastic extensibility of the sealing elements, that is of valve seat and / or valve member ensures that the valve member with some effort from the outside through the corresponding valve seat is carried out and the sealing elements in valve operation then have assumed their original shape, so that the valve chamber in the desired Type is securely sealed.
  • the necessary force to push the valve member through a valve seat can be applied from the outside, but it is also conceivable that this force by optionally amplified controlled actuators, which cooperate with the valve members, is applied.
  • valve members and valve seats make it easier to push the lifting rod through the valve chamber.
  • a bevel on the side of the valve member facing away from the associated valve seat which runs relative to the axis of the lifting rod and a corresponding slope of equal inclination on the side of the associated valve seat facing away from the valve member, the valve member is more easily passed through the valve seat can be passed.
  • valve member or the associated valve seat recesses configured can record material of the valve seat or the valve member during the passage of the valve member through the valve seat and thus lead to the valve member is easier to pass through the valve seat.
  • the sealing elements have again assumed their original shape, so that the valve chamber is securely sealed in the desired manner.
  • valve seat sliding friction it can be achieved by a chemical treatment of the sealing surfaces of the valve member and valve seat with a lubricant that a occurring during the implementation of the valve member by the valve seat sliding friction is minimized.
  • valve according to the invention allows in particular a pre-assembly of valves of valves of the type described in DE 197 53 575 Al:
  • the sealing rings, which form the valve seats and the spacer sleeve, which builds up the actual valve chamber, can be installed in the valve housing before the lifting rod ,
  • valve members On the lifting rod itself only the valve members are attached.
  • the valve members are pressed as ever at the desired location on the lifting rod, for example, and optionally caulked for securing additionally with material of the lifting rod.
  • the caulking provides a simple and reliable assurance of the valve members on the lifting rod.
  • the so mounted outside the valve housing lifting rod with the valve members mounted on it can then be used due to the elasticity of the valve seat or the valve member through the valve chamber into the preassembled valve housing.
  • the lifting rod of the valve according to the invention can be produced, for example, from a plastic. On the one hand, this leads to a reduction in material costs and, on the other hand, has the advantage that the valve members can be welded directly into the lifting rod, which in turn means a considerable simplification in the assembly of the valves.
  • the valve according to the invention thus enables a changed, faster assembly and thus has an improved quality and reduced costs in the production of the valves result.
  • the valve 10 according to the invention shown in cross section in FIGS. 1 and 2 has a valve housing 12, which has a valve chamber 14, into which an inlet channel 16, a first outlet channel 18 and a second outlet channel 20 lead.
  • the valve chamber 14 is inserted into the valve housing 12 and is formed by a, the first outlet 18 facing valve seat 22, - in Figure 1 or 2 below - a second outlet channel 20 facing the valve seat 24th - In Figure 1 or 2 above - and arranged between these two sealing elements spacer sleeve 26 which limits the actual volume of the valve chamber 14.

  • valve seats 22 and 24 of the valve chamber 14 are made in this embodiment of an elastically extensible material, for example of so-called NBR (acrylonitrile butadiene rubber) and each have a valve opening 60 and 62.
  • the valve chamber 14 is replaced by a further spacer sleeve 28 in the valve housing 12th fixed.

  • the valve member 36 cooperates with the valve seat 22 of the valve chamber 14 and controls the first outlet channel 18. This is closed, for example - as shown in Figure 2 - when a sealing surface 94 of the valve member 36 abuts against a sealing surface 96 of the valve seat 22.
  • the valve members 36 and 38 are made in the embodiment of the valve 10 according to the invention described herein made of plastic or of another rigid material such as brass.

  • a gap-shaped expansion region 83 between the valve housing 12 and the valve seats 22 and 24 is closed in this embodiment during the pushing of the valve member 36 through the valve seats 22 and 24.
  • the valve member 36 can be pushed through. After pushing the valve member 36 through the valve seats 22 and 24, these take on their original shape due to their elasticity.
  • valve members 36 and 38 together with the associated valve seats 22 and 24 can then seal the valve chamber 14 in the desired manner in the operation of the valve 10, for example, the sealing surface 96 of the valve seat 22 comes to rest on the sealing surface 94 of the valve member 36 and the first Outlet channel 18 closes.

  • the ramps 56, 58 and 59 have approximately the same slope and allow the lift rod 34 with the attached valve members 36 and 38 to be easier to guide through the valve chamber 14 during assembly.
  • the elastic material of the valve seats 22 and 24 is stretched and pushed apart so that the valve member 36 can be pushed by the expanded valve ports 60 and 62.
  • the surface 84 of the valve member 36 and the surface 86 of the valve seat 22 is provided with a lubricant.
